Modern man has no real "value" for the ocean. All he has is the most crass form of egoist, pragmatic value for it. He treats it as a "thing" in the worst possible sense, to exploit it for the "good" of man. The man who believes things are there only by chance cannot give things a real value. But for the Christian the value of a thing is not in itself autonomously, but because God made it.
